oxygen
Earths atmosphere is mostly nitrogen (78%) and Oxygen (21%).It is the oxygen that is the essential gas for breathing.
The gas in the atmosphere important to respiration is oxygen. It is taken in by animals during breathing and used in cellular respiration to produce energy for their cells.
Nitrogen is not essential for breathing, although it makes the atmosphere neutral as it acts as an inert medium. If there was a higher percentage of a reactive gas such as oxygen or chlorine, it would make a hazard for all living beings.
Oxygen is the gas in the atmosphere that is important for respiration. It is needed by cells to generate energy through the process of cellular respiration.
There are many uses of oxygen, from breathing by people with bad lungs or hearts, to operating cutting torches. I thought that commercial oxygen was removed from water, or other plentiful chemical, but not from the atmosphere.
Oxygen forms less than 1% of the atmosphere but is essential for life as it is required for cellular respiration in organisms to produce energy.
Yes, nitrogen is a gas that makes up about 78% of Earth's atmosphere. It is a colorless, odorless, and tasteless gas that is essential for life.
The atmosphere is made mostly of gas because gases have low molecular densities, allowing them to be easily suspended in the Earth's gravity. The gases in the atmosphere help regulate temperature and provide elements essential for life, such as oxygen.
carbon dioxide
Without the atmosphere mankind will be gone, no air mean no breathing, and no breathing mean no mankind.
An example of gas matter is evaporated water.
